Product details

Description

The LG LS120HFV3 single-zone wall-mounted mini split delivers reliable comfort all year long. Built with advanced inverter technology, it adjusts power smoothly so your room reaches the perfect temperature faster while using less energy. Rated at 17 SEER2, it provides energy efficiency that can help lower monthly bills without sacrificing performance. With cooling and heating in one unit, you enjoy comfort through every season. The sleek design blends seamlessly into any space, offering modern style without bulky equipment. Quiet operation keeps distractions away, making it ideal for bedrooms, offices, and living areas. Backed by LG’s reputation for quality, this system is designed to give you long-lasting performance and peace of mind.

This system is made to do more than just heat and cool — it’s about enhancing everyday living. Features like Jet Cool and Jet Heat give you rapid temperature control at the touch of a button. Auto Swing distributes air evenly throughout the room, eliminating hot or cold spots. A 24-hour programmable timer allows you to set your comfort schedule around your lifestyle. The auto changeover function switches between heating and cooling automatically, so you don’t need to adjust it yourself. When power outages happen, auto restart ensures the unit comes back on without hassle. Add in a self-cleaning indoor coil that helps maintain fresh airflow, and you get comfort that feels effortless.

Durability and quietness are built into the LS120HFV3. The GoldFin™ coating on the outdoor heat exchanger protects against corrosion, making it a strong choice in humid or coastal areas. Indoors, sound levels can be as low as 21 decibels in sleep mode — quieter than a whisper. That means no buzzing, no rattling, just consistent comfort. Outdoor sound remains low as well, so your backyard or patio stays peaceful. The unit is designed to operate across wide temperature ranges, from hot summers up to 118°F to chilly winters down to 14°F. Its compact, lightweight build makes installation easier for technicians and less intrusive for homeowners. These details add up to a system built for long-term reliability.

Convenience is another reason homeowners choose this LG mini split. The included wireless remote gives you full control without needing to leave your chair. Optional advanced controllers allow even more customization for those who want precise comfort management. Sleep Mode gently adjusts temperature overnight for energy savings and better rest. With energy-saving technology always running in the background, you get performance that works smarter, not harder. Whether for a single room, office, or studio space, this system is a cost-effective solution. It combines trusted performance with modern features that make everyday living simpler. Choosing LG means choosing a system designed with your comfort, budget, and lifestyle in mind.
